The power-point presentation for the workshops I conducted , which has everyday examples related to the concepts of coding, to make it easier for the students to understand.

Presented - Sanaa Sharda
Date: 13th January
The CODING Expert

2. Hi, I am Sanaa Sharda. I live in New Delhi and I’m in
class 11th.
My favourite subjects are physics, computer science
and economics.
I recently made a quiz, called ‘SMARTICUS’.
INTRODUCTION

3. What are we doing ?

4. Today we will be learning coding

5. WHAT IS THIS ?

6. Who uses computer?

7. Why is computer important?
Learning through phone, tablet or a
laptop

8. SMARTICUS - Quiz

9. Learning Coding - Future Job
Options/ Opportunities

11. WHAT IS CODING?

What is Coding? Explaining in Hindi - YouTube

12. TERMS:
1. ALGORITHM
2. SEQUENCE
3. LOOP
4. DECOMPOSITION
5. BRANCHING
6. DEBUG

13. 1. ALGORITHM
An algorithm is a sequence of steps :
● to perform a task
● given an initial situation (i.e., the input)

14. 1. ALGORITHM
An algorithm is a sequence of steps :
● to perform a task
● given an initial situation (i.e., the input)
Importance:
● An algorithm is used everywhere, we also use it in our
daily lives.
● They organize thought and action (computational
thinking)
● A computer program is an implemented algorithm

15. EXAMPLES OF ALGORITHM
The basic example of an algorithm is
“A RECIPE”
In a recipe to make tea, we first :
● Boil water,
● Add tea powder , ginger, etc.,
● Add milk and let it boil,
● Turn off the stove and strain the tea into
cups.
So, we see here that while making tea in our
everyday lives,we follow a set of steps which
can be called “an algorithm.”

16. EXAMPLES OF ALGORITHM

17. Quiz/ Revise
Pronunciation: Algorithm
Can someone explain the concept of Algorithm?
What example did we use?

18. 2. SEQUENCE
A sequence is a series of actions that is
completed in a specific order. Action 1 is
performed, then Action 2, then Action 3,
etc., until all of the actions in the sequence
have been carried out.

19. QUESTION
What is your morning routine ?

20. EXAMPLES OF SEQUENCE
A sequence we do every day is a morning routine.
You might wake up, drink some water, take a
shower, eat breakfast, and so on. Everyone's
routine is different, but they're all made up of a
sequence of various actions.
Another example is wearing clothes.
You first wear your undergarments, wear your pant
and shirt, wear socks and so on.
Every event takes place after the other in a
sequence.

21. Quiz/ Revise
Pronunciation: Sequence
Can someone explain the concept of Sequence?
What example did we use?

22. 3.LOOP
A loop is a programming structure that repeats
a sequence of instructions until a specific
condition is met. Programmers use loops to
cycle through values, add sums of numbers,
repeat functions, and many other things.
The same task/question is repeated again and
again.

23. EXAMPLES OF LOOP
Doing an 9am-5pm job,is an example of loop in
everyday life. We do the same job everyday and
get paid at the end/starting of the month.
Another example is your morning routine while
going to school. You wake up, get ready, eat your
breakfast, catch the bus, go to school and follow
the school’s timetable. These activities repeat on
each weekday forming a loop.

24. Quiz/ Revise
Pronunciation: Loop
Can someone explain the concept of Loop?
What example did we use?

25. Recap - 3 basic concepts in coding
1. Algorithm
2. Sequence
3. Loop

26. 4. DECOMPOSITION
Decomposition is the process of breaking
down complex problems into smaller, more
manageable parts.
This process of breaking down problems
enables us to analyze the different aspects of
them, ground our thinking, and guide
ourselves to a solution.

27. REAL LIFE EXAMPLE OF DECOMPOSITION
Hosting a party for friends/ wedding
function:
- Who will arrange/take care of food
- Who welcomes guest
- What time it starts
- Who all are you inviting
So you break down a big complex problem
into small manageable parts

28. Quiz/ Revise
Pronunciation: Decomposition
Can someone explain the concept of Decomposition?
What example did we use?

29. TECHNICAL EXAMPLE OF DECOMPOSITION
Addition calculation code:
4 + 3 = 7
- Code asks enter first
number
- Code asks enter second
number
- Code does addition
- Code displays result
(Remember input - output?)

30. 5. BRANCHING
Branching is a basic concept in computer
science. It means an instruction that tells a
computer to begin executing a different part of
a program rather than executing statements
one-by-one.
Common branching statements include break ,
continue , return, etc.

31. EXAMPLES OF BRANCHING

32. REAL LIFE EXAMPLE OF BRANCHING
Candy Crush Game
If you win LEVEL 1
go to LEVEL 2
Else
PLAY AGAIN
This is branching -
You have two different
options

33. Quiz/ Revise
Pronunciation: Branching
Can someone explain the concept of Branching?
What example did we use?

34. TECHNICAL EXAMPLE OF BRANCHING
Number 1 = 4
Number 2 = 3
If addition
4 + 3 = 7
If multiplication
4 x 3 = 12

35. 6. DEBUG
Debugging is the process of detecting and
removing of existing and potential errors
(also called as 'bugs') in a code that can
cause it to behave unexpectedly or crash.
It is a multistep process in software
development. It involves identifying the bug,
finding the source of the bug and correcting
the problem to make the program error-free.

36. EXAMPLES OF DEBUG
So far we only saw the basic concepts of coding.
Coding is like a language, just like English, Hindi,
Marathi. Coding is Computer’s language. So while
writing code we can make mistake. Debug is process of
rectifying those mistakes in code.
Just like our language, we make mistakes in grammar,
symbol (mathra) etc when young, how did you become
better now?
So you you keep learning and soon will become an
expert coder! Then you can do anything with computer!
